Vynález rieši zariadenie na prestavenie hornej čeíuste u ohýbacích strojov.The invention provides a device for adjusting the upper jaw in bending machines.
Je známe zariadenie na automatické vypínáme pohonu hornej čeíuste pri dosiahnutí nastaveného upínacieho tlaku pomocou odpružených matic s koncovými spínačmi. Toto zariadenie pracuje na tom principe, že po dosadnutí hornej čeíuste na plech, matice, vedené na zvislých vodiacich elementoch, pokračujú v pohybe a prekonávajú odpor pružných členov až dovtedy, kým sa dostatečné nevzdialia od koncových spínačov, ktoré vypnú pohon. Vtedy je horná čeíusť pritláčaná k plechu silou tiaže hornej čel'uste, a silou ktorú vyvodia stlačené pružné elementy. Toto zariadenie má tú nevýhodu, že dochádza k únavě pružných členov a tým k nerovnoměrnému pritláčaniu hornej čeíuste. Okrem toho toto zariadenie je vhodné iba u strojov, ktoré nemajú iným sposobom zaručený upínací tlak hornej čeíuste.It is known to automatically switch off the upper jaw drive when the set clamping pressure is reached by means of spring-loaded nuts with limit switches. This device works on the principle that after the upper jaw has been placed on the sheet, the nuts guided on the vertical guide elements continue to move and overcome the resistance of the resilient members until they are sufficiently removed from the limit switches which switch off the drive. In this case, the upper jaw is pressed against the sheet by the weight of the upper jaw and the force exerted by the compressed elastic elements. This device has the disadvantage that the elastic members fatigue and thus unevenly press the upper jaw. In addition, this device is only suitable for machines that do not otherwise have the clamping pressure of the upper jaw guaranteed.
Tieto nevýhody odstraňuje zariadenie podlá vynálezu na prestavenie hornej čeluste, najma u ohýbacích strojov s náhonom od předlohového planétového· převodu, kde tlak hornej čeíuste je daný převodovým pomerom a tým reakciou pohonu planétového ústrojenstva, pričom horná čelus, je vybavená dvoma pohybovými skrutkiami s maticami pre jej unášanie a na čelá matic dosadajú predížené čidlá koncových spínačov, přepojených v sérii ovládacieho okruhu brzdy ohýbacej čeíuste. Podstata vynálezu spočívá v tom, že matice sú uložené v hornej čelusti s axiálnou i radiálnou volou, podopreté axiálnym krúžkom a proti pootočeniu sú zachytené pomocou drážiek a spojok s obojstrannými výčnelkami, ktoré sú na druhej straně posuvné uložené v niektorej z dvojíc drážok objímok, pevne spojených s hornou čelusťou. Spojky sú axiálně pridžiavané k maticiam dělenými krúžkami, ktoré sú prichytené kompaktnými krúžkami.These drawbacks are eliminated by the device according to the invention for adjusting the upper jaw, in particular in bending machines driven by a planetary gear transmission, wherein the pressure of the upper jaw is determined by the gear ratio and thus the reaction of the planetary gear drive. its driving and nut ends are supported by extended limit switch sensors connected in series of the brake shoe brake control circuit. SUMMARY OF THE INVENTION The nuts are mounted in an upper jaw with axial and radial steer, supported by an axial ring and are secured against rotation by means of slots and couplings with double-sided protrusions, which on the other side are displaceably received in one of associated with the upper jaw. The couplings are axially retained to the nuts by split rings which are fastened by compact rings.
Zariadenie podlá vynálezu umožňuje rovnoměrné pritláčanie hornej čelusti.The device according to the invention permits uniform pressing of the upper jaw.
Příklad vyhotovenia zariadenia podlá vynálezu je znázorněný na priloženom výkrese, ktorý znázorňuje detail hornej čeíuste so zariadením podlá vynálezu. Zariadenie funguje takto:An exemplary embodiment of the device according to the invention is shown in the attached drawing, which shows a detail of the upper jaw with the device according to the invention. Here's how the device works:
Keď je horná čeíusť 2 nadvihnutá skrutkami 8, jej váha leží na spojkách 4, prostredníctvom puzdier 5, ktoré sú pevne spojené s hornou čelusťou 2. Pri zapnutí pohonu otáčavý pohyb skrutiek 8 vyvolává priamočiary posun oboch matic las nimi sa pohybuje horná čeíusť 2. Tento pohyb trvá tak dlho, kým pravítko hornej čeíuste 2 nedosedne na spracovaný plech. V okamihu dosadnutia pravítka, sa zastaví pohyb hornej čeíuste 2, avšak otáčavý pohyb skrutiek 8 a z toho vyplývajúci posuv· matic 1 smerom dole pokračuje, čo umožňuje axiálna vůla, s ktorou je uložená matica 1 medzi axiálnym krúžkom 3 a puzdrom 5. Po dosadnutí matic 1 na axiálně krúžky 3 sa predížené čidlá 9 koncových spínačov 10 posunů smerom dole a tým koncové spínače 10 dajú impulz na odbrzdenie neznázornenej elektromagnetickej brzdy ohýbacej čeíuste. Přítlak hornej čeíuste zostane konštantný od reakcie planétového ústrojenstva. Aby spojky 4 bezpečne sledovali pohyb matic 1, sú axiálně chytené dělenými krúžkami 6 pridržiavanými kompaktnými krúžkami 7.When the upper jaw 2 is lifted by the screws 8, its weight lies on the couplings 4, by means of bushes 5 which are fixedly connected to the upper jaw 2. When the drive is switched on, the rotary movement of the screws 8 causes a linear movement of both nuts and moves the upper jaw 2. the movement continues until the upper jaw ruler 2 is seated on the workpiece. When the ruler is fitted, the movement of the upper jaw 2 is stopped, but the rotational movement of the screws 8 and the resulting downward movement of the nuts 1 continues, allowing the axial clearance with which the nut 1 is positioned between the axial ring 3 and the sleeve 5. 1 to the axial rings 3, the extended sensors 9 of the downward displacement limit switches 10 and thus the limit switches 10 give an impulse to release the bending shoe electromagnetic brake (not shown). The upper jaw pressure remains constant from the reaction of the planetary system. In order to safely follow the movement of the nuts 1, the couplers 4 are axially engaged by the split rings 6 held by the compact rings 7.
